FRESNO, CA (KTRK) -- It's safe to say we could all use a little extra cash. But imagine going to your ATM, withdrawing money and getting more than double the amount you asked for.

The ATM at Bank of America in Fresno, California gave away $50 bills instead of $20 bills all day Saturday.

The bank isn't saying how much money was accidentally given away or what went wrong, but it's likely someone put the $50 in the $20 slot. Now the big question, should those customers give the money back?

"It was the machine, it was their bank mistake," said Bank of America customer Daniel Salas. "I don't think they should give the money back."

"I think it's better to do the right thing because eventually karma is going to get back to you," said another customer Martin Arce.

The bank says it has surveillance video and the personal information of all the customers who walked away with extra cash and it plans to get its money back.

No it would not, because you will have a receipt for $100 and anything else is insubstantial. You are not responsible to correct their mistakes. IMO.

I would like to hear the proper legal opinion on this.

Legally it falls under the "if you asked for $100" and got $250" then obviously it wasn't working correctly issues and you should have reported it. It's going to be hard to prove 100% that everyone checked their money prior to leaving, kind of like getting change back at the store and you realize when you get home they gave you a $20 instead of a $5.

Either way, they received the money, likely Bank of America will debit each account the proper amount and you know by now the people who got extra money have realized it. So it's on them to put the money back in their account and not be thieves, some of them will likely over-draw their account. They will probably just go in the bank and if they haven't spent the money yet, re-deposit it and they will waive the fees. The other's who went on a shopping spree knowing the money wasn't supposed to come out like that, deserve everything they get.

in the very small fine print it's stated that BoA is not responsible for errors and reserves the right to correct them when they occur...turns out bank error in your favor only really happens in monopoly

If you want to dispute it, then that's fine. The bank will haul you into court, show the dispenser loaded with $50s, show a record of your withdrawal that used that dispenser and a video of you at the ATM with $50 bills. After you lose, then they decide if they want to file criminal charges, in which they'll show the same evidence.
